BED CRANE FOR INVALIDS Filed. Aug. 6, 1948 2 SHEETS-SHEET 2 Inventor M'LA Robe/"f L- h OOJ By Q W W Attorney Patented Feb. 19, 1952 UNITED STATES PATENT OFFICE 1 Claim.

The present invention rerates to bed crane for invalids and it consists in the combinations, constructions and arrangements of parts herein claimed and described.

It is an object of the presentinvention to provide a bed crane which is practical, safe to use and which will lessen the danger of injury to patients in gettin on or off of bed pans.

Another object of the invention is the provision of an app ratus of the character set forth which will assist materially in the keeping of a patients bed in a sanitary condition.

Anotherobject of the invention is the provision of an apparatus of the character set forth which will enable an attendant to turn a helpless patient in his bed while at the same time creating a feeling of safety in the mind of the patient.

Another object of the invention is the provision of a bed crane for invalids which is simple and inexpensive in its construction and which is efficient and effective in use.

A further object of the invention is the provision of an apparatus of the character set forth which may be easily assembled and disassembled and which may readily be moved from place to place.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2 is a plan view thereof,

Figure 3 is a perspective view illustrating certain .details of construction,

Figure 4 is an enlarged fragmentary sectional view taken along line 4-4 of Figure 2, and

Figure 5 is an enlarged fragmentary sectional view taken along line 55 of Figure 4.

Generally there is provided a bed crane for invalids consisting of a vertical mast having a caster at its lower end and having a laterally extending V-shaped base plate provided with a pair of sockets for the reception of leg members each provided with a caster at its outer end. Brace members are removably interconnected with the outer ends of the legs and the mast. A head piece is affixed atop the mast and comprises a pair of spaced vertical plates between which is revolubly mounted a screw having an operating handle at one end and upon which is threaded a trunnion nut carried by one end of a bell crank lever which lever is pivoted to the plates and whose other arm acts as a crane arm,

the outer end of which is provided with an adjustable link which, in turn connects with a beam, The outer ends of the beam are each provided with a series of openings wherein may selectivelybe placed a pair of hooks which, in turn, act to hold therebetween a strap which may be placed beneath the invalid.

Referring more particularly to the drawings, there is shown therein a bed crane for invalids comprising a vertically extending mast Ill having a caster I I mounted in its lower end.

Welded or otherwise aflixed adjacent the lower end of the mast ll! is' a socket member l2 having a pair of sockets l3 and M extending radially at an angle therefrom and interconnected by a reinforcing web plate I5.

Leg members l6 and H are removably mounted in the sockets l3 and 14, respectively, and are held'in position therein by means of ,wing bolts 2 8 and i9, respectively.

Each of the leg members It and I! have respectively connected thereto at the outer ends thereof brace members 20 and 2| by means of Wing bolts 22 and 23, respectively, and the inner ends of the brace members 20 and 2| are connected to a projection 24 on the mast ID by means of a wing bolt 25. The outer ends of the leg members It and I! are provided with casters lfia and Ila, respectively.

An elevating mechanism is affixed to the top of the mast l0 and comprises a pair of vertically extending spaced parallel plates 26 and 21. A trunnion bearing 28 is provided with a pair of outwardly extending stub shafts 29 and 30 which are journaled, in thickened portions 3| and 32 of the plates 26 and 21, respectively.

Revolubly mounted in the bearing 28 is a shaft 33 which is provided with an integrally formed operating handle 34 at one end and has a large portion of its other end threaded and provided with a stop member 35 at its extremity. A collar 3% is integrally formed with the shaft 33 adjacent the handle 34 and a bearing 31 is revolubly mounted on the shaft between the collar 36 and the trunnion 28.

A bell crank lever is pivotally mounted, as indicated at 35 between the plates 26 and 21 and is provided with a relatively short arm 39 between the plates 26 and 21 and a relatively longer crane arm 4%? extending outwardly in a generally horizontal direction and above the legs l6 and H. The upper end of the arm 39 is bifurcated, as shown at M and 42, and has pivotally mounted in the parts 4! and 42 a trunnion 43 in which is threaded the shaft 33.

At the outer end of the crane arm 40 there is connected by a pin 44 a pair of links 45 and 46, one being carried at either side of the arm 40 and (each provided with a series of spaced openings A bar 48 is pivotally connected at its center by a pin 49 and is provided with a series of spaced openings 50 adjacent each of its outer ends.

A double-ended hook 5| is engaged in an opening 50 in either end of the bar 48 and a fabric strap 52 is provided with metallic reinforced ends 53 which have openings 54 for engagement with the hooks 5|.

In operation, it will be apparent that the apparatus may be kept, when not in use, in a disassembled condition and that when it is desired to use the same, it is only necessaryto place the leg members I6 and IT in the sockets l3 and I4 and thereafter lock the same in position by means of the wing bolts I8 and I9. Thereupon the brace members are placed in position and locked by means of the wing bolts 22, 23 and 25. The apparatus may then be wheeled by means of the casters H, Mia and Na to bring the legs [6 and I1 beneath the patients bed. The strap 52 may then be placed beneath the body of the patient by carefully rolling him upon it and thereafter the ends 53 thereof may be engaged with the hooks 5|. By turning the handle 34 in the proper direction, the trunnion 43 will be caused to move in the direction of the handle end of the shaft 33 thereby causing the arm 39 and consequently the crane arm 49 to move in a counterclockwise direction as viewed, for example, in Figure 4. This action will lift the bar 48 by means of the links 45 and 46 and therefore cause the strap 52 and the patient to be lifted from the bed whereupon an attendant may do whatever is necessary for the patient such as, for example, the proper placing of a bed pan beneath him. By placing the pin 44 in the proper openings 41 the effective height of the bar 48 may be adjusted and by placing the hooks in 4 selected openings 50 the eflective width of the strap 52 may be regulated.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

An apparatus of the character described comprising a vertical mast, a socket member aflixed to the mast adjacent the lower end thereof, a pair of horizontally and angularly extending leg members removably mounted in the socket member, a caster supporting the mast, a caster supporting each of the leg members, brace members removably interconnecting the mast and the outer ends of the leg members, a pair of vertical plates affixed to the upper end of the mast in spaced parallel relation to each other, a threaded shaft formed with a handle-and extending between the plates and pivoted thereto, a crane arm extending between said plates and pivotally connected thereto, and said crane arm provided with an angular extension formed with a threaded opening adjacent the free end thereof threadedly receiving the shaft.
